▶ Drain oil through the oil drain (8).
▶ Loosen the four screws (4) on the flange (3) of the
maintenance connection for the oil filter. Pull the

▶ Clean the oil filter chamber.
▶ Replace flat gasket (5) and O-rings (6) and insert a
new oil filter (1). Position the flat gasket in the hous-
ing according to the alignment pin (9).
▶ Fix the entire unit in the three grooves (10), turn it
20° counterclockwise and press it down, while fixing
the alignment pin (9) in the hole provided for it on the
